More than one suction unit is all made of the rubber material system with deformation recovery capability as a preferred technical solution,
At the gas in suction chamber is extruded and passes through the air-breathing seal of tube.
The inside of bulge has a closed gas storage chamber as a preferred technical solution, in gas storage chamber
Gas is stored, entire bulge is made of an elastic rubber material.
Gluing water-stop between the outer wall of cable and outlet aperture inner wall as a preferred technical solution,.
The two sides on the installation pipe close to suction unit are respectively arranged with more than one as a preferred technical solution,
Gas aperture seals small ventilating holes after suction unit expansion.
The beneficial effects of the present invention are: bulge suspension support of the one, present invention by each softness, has extraordinary anti-
Shake ability realizes by each bulge to the package of cable outer wall, plays and preferably protect to cable have extraordinary protection
Performance；
Two, the present invention enables to bulge to expand when cable is superheated to extreme position, and then each suction unit is connected,
It realizes the pumping to intracavitary portion is routed, blocks the burning condition of flame, play better fire protecting performance.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Fig. 1 is overall structure diagram of the invention；
Fig. 2 is the schematic diagram of internal structure before not turning between bulge and suction unit of the invention；
Fig. 3 is the schematic diagram of internal structure after bulge of the present invention is connected with suction unit.
Specific embodiment
As depicted in figs. 1 and 2, a kind of cable, including an installation pipe 2, the inside of installation pipe 2 have the wiring of a sealing
Chamber 3, the two sides of cloth line chamber 3 seal and are reserved with outlet aperture, and cable 7 is set in cloth line chamber 3 and is discharged from outlet aperture,
The serving hermetically passing outlet aperture of cable 7,3 inner wall surrounding cloth line chamber one of cloth line chamber circle fixed bonding have more than one suction
Gas portion 1 faces each suction unit 1 in the outside wall surface of cable 7 and is provided with a bulge 8, between bulge 8 and suction unit 1
Bulge 8 is connect by the air intake duct 5 of insertion one or more, air intake duct 5 with air intake duct 5.
As shown in Fig. 2, a sealing axle sleeve 4 is arranged in 5 relative expansion portion of suction unit, 8 side, there is one inside sealing axle sleeve 4
The sealed passage of both ends open has a suction chamber 11 inside suction unit 5, and sealed passage is communicated with suction chamber, air intake duct 5
It is inserted into suction chamber 11 across sealed passage.
The outer wall of air intake duct 5 and sealed passage inner wall are in sealing contact, and air intake duct 5 is rubber tube, and air intake duct 5 is by sealed passage
Sealing, when sealing state, suction unit is in the state of compressive deformation, at this time entire cloth line chamber and it is extraneous be connected, may be implemented normal
Heat dissipation；
In the present embodiment, air intake duct 5 is inserted into suction chamber side and is provided with an air guide port 13, and the outside of air intake duct 5 is stretched
Outlet setting one has the air induction conduit 6 of breather cheek valve, and air entry 5 is inserted into sealed passage and by sealing axle sleeve 4
Wall sealing.
When cable overheats, and reaches combustion state fastly, bulge internal gas constantly expands, and bulge will drive air-breathing
Pipe is finally inserted into air guide port in suction chamber towards movement inside suction chamber, and suction unit is connected air intake duct at this time, this
When, suction unit can suck a large amount of gas to restore deformation from air induction conduit, and then extract out and be routed intracavitary gas, due to
Provided with breather cheek valve, therefore the reflux of gas can be effectively prevented, blocks the fluid of gas, and then block flame combustion
It adjusts, as shown in Figure 3.
In the present embodiment, more than one suction unit 1 is all made of the rubber material with deformation recovery capability and is made, air-breathing
Gas in chamber 11 is extruded and passes through the air-breathing seal of tube, and the inside of bulge has a closed gas storage chamber 12, gas
12 memory storing gas of body storage chamber, entire bulge are made of an elastic rubber material, and when gases are heated, they expand, and rate is larger, therefore
When reaching sufficiently large heat, it is expanded to extreme position, air guide port can be connected at this time.
Wherein, gluing water-stop between the outer wall of cable 7 and outlet aperture inner wall, guarantees the sealing after blocking air
Property, the two sides on installation pipe close to suction unit are respectively arranged with more than one small ventilating holes 21, seal after suction unit expansion saturating
Gas aperture 21, when bulge does not expand, small ventilating holes conducting is realized the proper heat reduction of cable, upon expansion, is immediately sealed
Small ventilating holes simultaneously block small ventilating holes, and preventing external air from passing through small ventilating holes, to enter wiring intracavitary.
The beneficial effects of the present invention are: bulge suspension support of the one, present invention by each softness, has extraordinary anti-
Shake ability realizes by each bulge to the package of cable outer wall, plays and preferably protect to cable have extraordinary protection
Performance；
Two, the present invention enables to bulge to expand when cable is superheated to extreme position, and then each suction unit is connected,
It realizes the pumping to intracavitary portion is routed, blocks the burning condition of flame, play better fire protecting performance.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.Therefore, of the invention
Protection scope should be determined by the scope of protection defined in the claims.
